Williams JHW1213MSC Combination Wrench 13 Mm 12-point

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1213MSC is a 13 MM combination wrench featuring a 12-point box end and a SUPERCOMBO open end, built for trade professionals who need reliable torque application on hex fasteners. The box end uses a SUPERTORQUE design that contacts flat fastener surfaces rather than corners, reducing the risk of rounding or deforming fastener points under high torque. The open end incorporates specially designed grooves that redirect wrenching force away from fastener corners. Finished in high-polish chrome, this wrench is suited for mechanical, HVAC, plumbing, and electrical service work where metric fasteners are common.

This combination wrench is appropriate for residential and commercial service applications involving 13 MM hex fasteners. The 12-point box end offers versatility in tight spaces with limited swing arc, while the SUPERCOMBO open end provides added grip on worn or damaged fastener heads. It is rated to ANSI B107.6 and SAE AS 954, making it a suitable choice for shops and field technicians who require compliance with federal specifications.
